Runtime Debug Tools for Godot

A proof-of-concept Godot addon that attempts to extend and improve the runtime
debugging experience.

Features

• Works with both 2D and 3D scenes.
• Debug camera. A simple in-game debug camera for navigating around the live
  scene. This somewhat mimics the in-editor camera experience.
• In-game object picker. While using the debug camera, clicking the mouse will
  select the object under the mouse, highlighting it with a visible gizmo in the
  runtime and selecting the object in the Godot Editor remote tree inspector.
• Editor object picker synchronised with the running application. Selecting a
  node in the Godot Editor, will visually select it in the runtime debug view
  with a visible gizmo.
• Optionally, turning on 2D or 3D Debug mode pauses the running game. This makes
  debugging easier, and also prevents running game code from interfering with
  debug controls.
• Runtime toggling of debug features. The remote inspector popup menu exposes
  various debug visualisation options. Including:
  • Wireframe mode.
  • Collision shapes.

Videos

• Debug Camera
• In-game object picker
• Editor selections synced with game
• Runtime debug visualisations
• 2D tools

Installation and Usage

• Download from the Godot Asset Library.
• Import the plugin into your Godot project.
• Enable the plugin in your project settings.
• When the game is running click on the RDT button in the toolbar and select
  '2D' or '3D' debugging.

Notes

• One of the features of this tool is to synchronise the selected item in the
  'remote scene tree' with the running game. In order to do that, the remote scene
  tree needs to be open, otherwise you'll see a warning "Node not found. Please
  check the remote tab is open". There are two ways of doing this:
  1. Every time you run the game, select the 'Remote' tab in the scene tree.
  2. Automate 1 so the remote scene is selected every time you run the
     game. Go to Editor Settings, and set
     debugger/auto_switch_to_remote_scene_tree to true
• 3D object picking uses physics meshes, as well as rendered MeshInstances. This
  has the benefit of being accurate and working with all rendered assets without
  requiring any scene modifications; however triangle picking may be slow in
  large/complex scenes.
• 2D object picking is currently limited to sprites and UI controls.
• Some features, such as selecting nodes in the editor scene tree, and toggling
  collision meshes, rely on undocumented Godot features.
• This is just a proof of concept. The hope is that some of these features might
  eventually appear in core Godot as first class features.
